The Hach Sigma 900MAX Portable Sampler’s advanced technology and comprehensive customer service can be summarized in five key concepts: accuracy, simplicity, flexibility, reliability, and economy.

Easy, menu-type programming uses a large backlit display. Use the Hach Sigma 900MAX sampler to monitor and log rainfall, level, flow, velocity, temperature, pH or ORP, with 12 data logging channels. Depending on model, up to seven external analog signals can also be logged. As many as 116,000 readings may be recorded.

Unique Constant Time / Variable Volume Sampling

The patented Constant Time/Variable Volume sampling method varies sample size in proportion to flow rate. This feature takes regularly timed, proportional samples depending on the flow rate, ensuring that representative samples are taken at even intervals throughout the sampling period.

Field Convertible for Compact or Discrete Sampling

Weighing only 28 pounds (12.7 kg), the 900MAX Portable Sampler is designed for accuracy and convenience. Quickly switch between composite and discrete sampling in the field. Configurable for single- or multiple-bottle applications, it is specifically designed for use in 18-inch manholes.

The non-contact ultrasonic liquid sensing system guarantees volume accuracy and repeatability. Reduce cross-contamination with a line rinse; the intake is preconditioned with the source liquid prior to collection. In the event that a plugged intake prevents collection, the unit detects the failed attempt and immediately repeats the cycle starting with a high-pressure purge.

Customizable Set Points

Collect samples in response to changing levels of selected parameters—set high and low trip points to immediately collect when a parameter exceeds preset limits.

Easy Data Management Software

Powerful, user-friendly software makes it easy to analyze the data and produce presentation-quality reports for any time period, or generate customized reports integrating sample collections with a variety of parameters.

Allows use of two samplers in combination; at the completion of its program, the first sampler initiates the second

Upset Sampling

When equipped with integral flow meter or pH/temperature/ORP monitoring options, or triggered from an external control device, sampling can be started in an upset condition when field-selectable limits are exceeded. Concurrent with normal sampling routine, sample liquid is deposited in designated “Trouble Bottle(s)”

Choice of Teflon® and 316 stainless steel construction, or all 316 stainless steel in standard size, high velocity, and low profile for shallow depth applications

The Hach Sigma 900MAX Portable Sampler is designed for indoor or outdoor use. No secondary enclosure is required when operated within the specified temperature range. The sampler consists of three main sections—the top cover, the center control system, and the bottle/base section held together by stainless steel latches which serve as the connection point for the optional suspension harness. The lockable top cover protects the controller from extreme weather and unauthorized use.
